The [[_LIMIT]] statement sets the loop repeat rate of a program to so many per second, relinquishing spare CPU cycles to other applications.
{{PageSyntax}}
: [[_LIMIT]] {{Parameter|framesPerSecond!}}
* The {{Parameter|framesPerSecond!}} [[SINGLE]] parameter value adjusts the loops per second of a program loop. '''Do not use negative values.'''
* The loop code is executed before the loop is delayed. Loop cycles below once per second may delay program [[_EXIT]]s.
* _LIMIT measures its interval from the previous time that it was called and minor adjustments are automatically made to ensure that the number of times a loop is repeated is correct overall.
* Loop cycle rates of 1000 or less can '''significantly reduce CPU usage''' in programs.
* Do not use it to limit a loop to '''less than once every 60 seconds'''(.0167) or an [[ERROR Codes|ILLEGAL FUNCTION CALL error]] will occur.
* Do not use _LIMIT as a timing delay outside of loops. Use [[_DELAY]] instead.
* Use _LIMIT to slow down old QBasic program loops that run too fast and use too much CPU.

''Example:'' Limits loop execution to 30 frames per second and limits the program's CPU usage.
